Application filed AprilBO. 1906- Serial lib-314.332.

I dohereby declare thelollowing to be a full,

clear, and exact description of the same, rel"- v.erence being had to the accompanying drawin gs forming a part o'l this specification, and to the rreference-numerals marked thereon.

My presentunvention relatvs to 1m provementsin and particularly to the tions 'in nori'nal position. Fig. 3 is a "\iQW' similar to Fig. 2, showing'the guards sepa l outer ends of the lenses.

type employing a s Wing-bridge vi-"herein rela tlVG movement oi t '10. lenses serves to operate the-- 'uards in. iittirw-andremoving the eyeglasses; and the mm. of the present inven jtion is to provide an improved mounting of I the lower end. ol this arm is doubledm: Wardly between the. two arms of the spring this gen eral type cmbo dym g certain im prove- "Inents thatvvill atl'o'rd ample action to the bridge and provide means for limiting the 7 relative movement of the lenses. to avoid breakage of the bridgeeither through accident ofoarelos'sness.

To these and other ends ltCOIlSlStS 1n the improvements hereinafter described, the;

novel features being pointed out in the claims. p

' Inthe drawings, Figure l is a front elevation of a pair of eyeglasses embodyinginy invention. Fig. 2 is an enlarged rear elevation of the moun ting with the nose-'engagingporrated by arelative movement of the lenses substantially in line with their ma or axes.

Fig. i represents a transverse section oi" lhe mounting as VlE-WBd from the le'lt in Fig. 2 and Flg. 1s a plan new of the mounting,

showing the nose engaging portions separated by a relatively forward tilting the The present embodiment of my invention 1 taching-arms 8 and 9, the latter entering the from. their under side and are secured by the usual lastemng-screws. v

The improved guard adapted tobe emin place wardly and upwardly to form the spring at boxes of their respective attaching devices.

i ployed in connection with a -spring-of" the.

kind just described is preferab y formed of f ilat material and. comprises, in the present instance, an attacl'iing portion. 10, substantially the form of an" inverted loofoneof the anus of the loop entering the top' ofthe box and the other arm of the loop extending to the roar of the attaching device and then or; tending downwardlyin rear of tle'attach I ing device .to form an outer arm at the outer side of the 1' an arm of the spring,- and and then eflended, preferablylcarwardl acont rear arm of the spring to form. an arm i 11, provided with a nose-engaging pad or surface 12, the spaced arms 10 andrll'of. each guard resting in substantially parallel planes and on opposite sidesof the respective rear l arm of the spring. tion of each guard rests-at the.-outer side of the spring and is arranged to engage the latter as a fulcrum when the lensosiare turned The. inverted .lo'op por i or deflected into the position shown in Fig '5', while l'he sp ac'od arms 10 and 11' of each guard serve to limit the movementof the I line \yilh their major axes.

1 kind shown and describml a comparatively j long resilient loop is formed brilm doubled i. arms of the spring that will iusuroil'le great- 1 est separating movement 01 the guards when correspmuliug arms (5 and 7 of the spring ln employing a'spring substantially of the the lenses are either (lltl-WIPJLPQIT- in the line Vided. at their proximate eil'ges'with lens-atof their major axes in the manner shown in .tflOhIDg-(lGVIGGS 3 and 4, preferably of the Fig. 3 or by turning or deflecting them as usual construction and having boxes at their shown in Fig. 5, without unduly straining inner ends to receive the attaching portions 1 the bridge, "as the, guards serve as'slops to of the spring and guards. The spring emlimit the. movement of the rear arms of the ployed in the present embodiment comprises spring-hams" beyond a prvdol'ermiued point the centralbowed port-ion 5, adapted to span when the lenses are drawn apart in the line the nose and having its extremities extended of their major a-xesnaud when the outerends .in a-hdirection downwardly and rearwardly of thelenses are bent forward the upper behind andin proximity to theattaglung delooped portions of the guards will engage the vices to form the rear arms 6 a ujl '7, which. i outer sides of the spring as i'ulcrums, and- "are extended some distance below-the attaoh- 5 consequently they movement of the guards ing devices, then do'uhied preferably fpr' I will be insured about these fulcrums as ccn' lens, and this Will prevent inward movement of (he attaching devices when the lenses are tilted in this manner, as this would be objeclionable in that the ell'ective separating, movement of the guards would be decreased by an inward movement of their attached ends. in a springol' this form the extensive surface al'l'orded by the loops may be utilized as. hose-engaging surfaces, especially when the spriin; is formed of flat material, as is relerable, and as the pads 12 whenin operalive position on the wearers nose lie substantially in the same plane with the looped portions ol the spring they may obtain eli'ective hold on the nose, as the looped porlion. oi the spring and the pad of the guard iorm sulmtamiially a continuous nose-engagng surl'z-icc.

7. In eyeglasses, the combination with the lenses, and a bridge-spring connecting them embodying a central portion, substantially vertical =loops arranged between the inner edges of the lenses, one arm'of each" loop being attached toits respecti e lens, and. a relatively movable arm connected to the central portion and extending'into proximity to the points 'of attachment for the spring, of noseguards secured to the lenses each embodying an arm arranged at the outer side of the relaengaging portion arranged at theinner side of the movable arm of the spring.
